You must determine the air flow through the existing furnace before installing the MAX CADDY add-on:
1. Run the add-on to which the MAX CADDY add-on is connected until it reaches its regular heating temperature.
2. With a thermometer, measure the temperature of the fresh air entering the furnace and that of the air exiting the
add-on in the hot air plenum.
Note: There can be a large lag in the readings of many commercially available thermometers. Give them adequate
time to stabilize when taking temperatures.
The temperature rise is obtained by subtracting the cold air return temperature from that of the air exiting in the hot air
plenum. The result (t) will be needed for next step.
3. Make the following verifications:
Existing oil, electric or gas furnace:
Q=
______q_____
1.08 x (T2 – T1)
Q = Flow in cubic feet/min
q = Heat flow in BTU/h
T1= Fresh air return temperature
T2= Hot air outlet temperature
12.2. MINIMUM CLEARANCES TO COMBUSTIBLE MATERIALS AND FLOOR PROTECTION
N.B.: This appliance must be installed in accordance with the instructions on the certification plate
applied on the unit.
12.3. INSTALLING THE CONNECTING DUCT FROM THE EXISTING FURNACE
To install the connecting duct from the existing furnace on the left or right side of your Max Caddy Add-on, remove the
screws (A) securing the large panel (B or C) of the add-on. Connect the ducts.
